Product details
Overview
7052L25PFGI from Renesas Electronics is a high-speed 2K × 8 (16 Kbit) FourPort™ static RAM IC with four fully asynchronous, independent ports (P1–P4), 25 ns maximum access time, industrial temperature range (–40°C to +85°C), and low-power standby current of 1.5 mW (typ.) per port. It enables simultaneous read/write access to shared memory in real-time multiprocessor systems such as radar signal processors and avionics data concentrators.
For engineers reviewing the 7052L25PFGI datasheet, 7052L25PFGI pinout, 7052L25PFGI application, or 7052L25PFGI equivalent, this page delivers verified technical context, validated pin functions, confirmed timing parameters, and real-world use cases for deterministic multiport memory selection in safety-critical embedded systems.
Technical Context
The 7052L25PFGI implements true FourPort architecture with separate address, data I/O, control (CE/OE/R/W/BUSY), and power domains per port - enabling concurrent, contention-aware access without on-chip arbitration logic. Each port operates asynchronously with independent chip enable (CEP1–CEP4) and output enable (OEP1–OEP4) signals.
It supports battery-backed data retention at VCC = 2 V (typ. 25 µA retention current), TTL-compatible 5 V ±10% single-supply operation, and automatic power-down via CE assertion. The device uses CMOS process technology and requires external arbitration when multiple ports access the same memory location simultaneously.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar FourPort SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IDT7052L25G | Same core spec, but 108-pin PGA (GU108) package; no TQFP footprint compatibility | Suitable for through-hole or socketed military PCBs requiring higher mechanical robustness | Select for legacy board reuse where PNG120 rework is prohibitive |
| CY7C1375D-25BGXI | 2.5 V core, 3.3 V I/O; 25 ns access; 2K × 18 depth; different pinout and BUSY implementation | Requires level-shifting and layout redesign; targets newer low-voltage systems | Choose only if migrating to 3.3 V infrastructure and needing wider data bus |
Compared with IDT7052L25G and CY7C1375D-25BGXI, the 7052L25PFGI uniquely combines industrial temperature rating, 120-pin TQFP packaging, and 5 V TTL compatibility - making it the only drop-in solution for upgrading legacy 5 V avionics backplanes without altering PCB layout or power architecture.

FAQ
What is the operating voltage range for the 7052L25PFGI?
The 7052L25PFGI operates from 4.5 V to 5.5 V (5 V ±10%) on a single supply. It does not support 3.3 V or mixed-voltage operation. All I/Os are TTL-compatible, and VCC must be stable within this window during active and standby modes to guarantee timing compliance and data retention integrity for the 7052L25PFGI.
Does the 7052L25PFGI support battery backup operation?
Yes, the 7052L25PFGI supports data retention at VCC = 2 V (minimum), drawing ≤600 µA typical current in retention mode. This allows seamless transition to backup power during main supply interruption - a key requirement for avionics and industrial control systems relying on the 7052L25PFGI for nonvolatile state storage.
How many independent ports does the 7052L25PFGI have, and what signals define each?
The 7052L25PFGI has four fully independent ports (P1–P4), each with its own 11-bit address bus (A0–A10), 8-bit bidirectional data bus (I/O0–I/O7), and dedicated control lines: Chip Enable (CE), Output Enable (OE), Read/Write (R/W), and BUSY input. No shared control logic exists between ports - all timing and arbitration are externally managed for the 7052L25PFGI.
What is the meaning of "L" and "25" in the part number 7052L25PFGI?
In 7052L25PFGI, "L" denotes the low-power version (1.5 mW standby vs. 7.5 mW for "S"), and "25" specifies 25 ns maximum access time. "PFGI" indicates PNG120 package (P), green RoHS-compliant finish (G), and industrial temperature grade (I). This exact combination defines the electrical, thermal, and mechanical behavior of the 7052L25PFGI.
Is the 7052L25PFGI pin-compatible with other members of the IDT7052 family?
The 7052L25PFGI shares identical pinout and signal mapping with all other PNG120-packaged IDT7052 variants (e.g., 7052S25PFGI, 7052L20PFGI), differing only in speed grade and power class. However, it is not pin-compatible with GU108 PGA versions due to distinct land patterns and pin counts - migration requires PCB redesign unless using socket adapters for the 7052L25PFGI.
